I have been using vROPS for a few months now and noticed that under "Capacity Remaining" tab there is a section "What Will Fit".
As you can see vROPS has already done some analysis based on the metrics it has collected in your environment. If you click on the down triangle it will tell you what metrics it is using to base on that assumption
From the above diagram "Average Profile" it tells us that my cluster is over provisioned by 81 VMs and the specs it has used to help give the number. As you can see this is based on "Demand". In my environment we are doing capacity by "Allocation" and also we deploy VMs with specific configurations for different clusters. So how do we do that ?
On the same screen click on the right or left arrows until you see the "+" sign and click on this
A new screen will prompt up
- Give the profile a name which will be display name as well
- Leave the object type as "Virtual Machine"
- Decide if you want this to be used for all policies and if they are then tick box "Enable this profile for all Policies" otherwise under the "Advanced" section decide which policies you would like to enable or hide the profile from.
Use the scroll bar to go further down the options
- Under Metrics section decide on the filter (model) which is either "Allocation" or "Demand". In my case we are using "Allocation" so I will select this one.
- You have a option to then either import metrics from an existing VM or type in the values you wish to set then click "OK"
You will now see your newly added profile under the "What Will Fit" but the number of VMs are shown as "?". Depending on the size of your environment that should change to a number once it has worked out what is should be
What if I want to change the setting of this?
- Click on "Content" icon
- Select "Custom Profile" and on the right navigation panel highlight the server you wish to edit. Click on the "Pencil" to edit
- You can now editing the settings and then click "OK"
